UNITED STATES PATENT OFFICE.

JOHN W. RENSHAW AND SAMUEL H. PERIN, OF JEFFERSONVILLE, IND.

MACHINE FOR GRINDING SAD-IRONS.

SPECIFICATION forming part of Letters Patent No. 338,301, dated March23, 1886.

Application filed June 8, 1885. Serial No. 167,978.

To all whom it may concern:

Be it known that we, JOHN W. RENSHAW and SAMUEL H. PERIN, both of Jeffersonville, in the county of Clarke and State of Indiana, andcitizens of the United States, have jointly invented certain new anduseful Improvements in Machines for Grinding Sad-Irons, ofwhich thefollowing is a specification.

Our invention consists in an improved de vice for feeding the sad-ironsto the grindstone, and in the various combinations of mechanism,hereinafter set forth, and pointed out in the claims.

In the drawings, Figure l isa side elevation of the feeding device, thesliding frame upon which the same is mounted, and a portion of thegrindstone; Fig. 2,afront elevation of the same; Fig. 3, a reduced Viewshowing one method of imparting lateral motion to the grindstone; Fig.4, a bottom view of the plate for holding irons; Fig. 5, a side view ofthe same, and Fig. 6 an end view of the guides for the plates carryingthe irons.

A represents a grindstone mounted upon a shaft, or, to which revolvingmotion is imparted by any usual meansas by a belt running upon a pulley,a. A reciprocating motion is also imparted to the shaft by the cocentricB and worm-gears b and b, or other suitable means. Thus the grindstonehas both a revolving and a laterally-reciprocating motion.

0 C represent a pair of endless chains carried by sprocket-wheels D Dand rollers DD, mounted upon a suitable frame, E, which is madeadjustable with reference to the grindstone by means of any suitableadjusting mechanism.

The chains C are preferably composed of alternate single anddoublelinks, and the sprocket-wheels D have forked sprockets adapted toembrace the single links. A series of plates, F, for holding sad-irons,is mounted upon the chains 0, each plate preferably extending from chainto chain, and adapted to carry two or more irons.

(No model.)

In the form shown, f represents the base of the plate provided withaperture f, adapted to receive the handles of sad-irons, and havingahinged T-arm, f, adjustable with refer- 5o ence to the plate by meansof aset-screw, f

Attached to the frame E are guides orslides e, adapted to receive theplates F as they approach the grindstone and guide them in a fixed pathduring the contact of the sad-irons 5 with the stone.

To claim as our invention-.-

1. In a machine for grinding sad irons, the combination of a grindstonehaving a rotating and a laterallyreciprocating motion, with one or moreendless chains carrying a series of plates for holding sad-irons.

2. In a machine for grinding sad-irons, the combination of a grindstonehaving a rotating and a laterally-reci procatin g motion, with one ormore endless chains carrying a series of plates for holding sad-irons,and carried by sprocket-wheels and rollers mounted upon a sliding frame.

3. In a machine for grinding sad'irons, the

combination of a-grindstone having a rotating and alaterally-reciprocating motion, and one or more endless chains carryinga series of plates for holding sad-irons, and carried by sprocket-wheelsand rollers mounted upon a sliding frame, with guides adapted to confinesaid plates to a straight path during the contact of the irons with thegrindstone.

4. In a machine for grinding sadirons, the

combination 'of a pair of endless chains, of a JOHN W. RENSHAW. SAML. H.PERIN.
